Metabolite Identification
Common NamePyridoxal 5'-phosphate
DescriptionPyridoxal 5'-phosphate, also known as phosphopyridoxal or PLP, belongs to the class of organic compounds known as pyridoxals and derivatives. Pyridoxals and derivatives are compounds containing a pyridoxal moiety, which consists of a pyridine ring substituted at positions 2,3,4, and 5 by a methyl group, a hydroxyl group, a carbaldehyde group, and a hydroxymethyl group, respectively. Pyridoxal 5'-phosphate is a drug which is used for nutritional supplementation and for treating dietary shortage or imbalance. Pyridoxal 5'-phosphate exists as a solid, possibly soluble (in water), and a strong basic compound (based on its pKa) molecule. Pyridoxal 5'-phosphate exists in all living species, ranging from bacteria to humans. In cattle, pyridoxal 5'-phosphate is involved in the metabolic pathway called the glycine and serine metabolism pathway. Pyridoxal 5'-phosphate is a potentially toxic compound. Pyridoxal 5'-phosphate has been found to be associated with several diseases known as rheumatoid arthritis, epilepsy, early-onset, vitamin b6-dependent, odontohypophosphatasia, and pyridoxamine 5-prime-phosphate oxidase deficiency; also pyridoxal 5'-phosphate has been linked to the inborn metabolic disorders including celiac disease.
